Luo Bin asked He Chufeng if he liked girls like Sui Yi, but He Chufeng didn't answer, so Luo Bin encouraged him to pursue true love. Wang Wenxin came in a hurry, and Li Yun confessed his past. The first time they met was the most difficult time for Li Yun, because when Professor Jiang died, it was the parallel world that Li Yun said comforted her. Li Yun also used him to accompany him through the most difficult moments. Li Yun hopes that Wang Wenxin can be himself, he is a very special and simple person. Li Yun then thanked He Chufeng and Luo Bin. Now she understands that she should look for her future self, and hopes that He Chufeng can forget the past.
Wang Wenxin didn't catch up. He thought that Li Yun didn't love him. The key she left behind was the lock on the door, and Wang Wenxin never entered it. He Chufeng told him that the door had never been locked, and he was the one who locked him out. Wang Wenxin finally plucked up the courage to catch up with Li Yun, he wanted to know the real Li Yun. Ji Xiu gave He Chufeng a magpie lock. It is said that he bought it from a locksmith many years ago.
He Chufeng investigated his master and learned his current address. ten years ago. He Chufeng learned how to open locks with his master in Gu's lock shop. Sui Yi has been thinking about what He Chufeng said, and has been avoiding him recently. When He Chufeng met Sui Yi while shopping for vegetables, Sui Yi still kept her head down and did not dare to look him in the eye. He Chufeng thought she was sympathizing with him and was a little angry. But Sui Yi's real emotion was guilt, because she had asked about He Chufeng's life experience before, and felt sorry for him. He Chufeng said that the past is his past, and his sorrow is also his sorrow, so Sui Yi doesn't have to be sad about it. Only then did Sui Yi let go of her melancholy mood, and became chattering again. At night, He Chufeng thought that the person who bumped into them just now was very calm and lost the lock, but he knew that this person would appear by himself.
Early in the morning, Sui Yi entered the bathroom in a daze, and ran out in a panic after seeing a picture of a beautiful man getting out of the bath. At breakfast, He Chufeng saw Luo Bin and Sui Yi having a happy chat and became jealous silently, even throwing away the bread in his hand. Sui Yi has been hiccupping since the morning, as if he was frightened by He Chufeng, after all, it was a very tempting scene. Someone was following He Chufeng. She once hoped that he would teach her to open the lock, but He Chufeng refused.
Sui Yi slept every day from morning till night, Luo Bin couldn't help asking her if she saw something exciting, Sui Yi glanced at He Chufeng and hurriedly denied it. Seeing the two together, He Chufeng began to observe. In order to stop the hiccups, Sui Yi tried many methods, and even let Robin hit herself. Luo Bin refused to let go, Sui Yi put her head into the refrigerator again, He Chufeng appeared from behind her, stared at her for a few seconds, Sui Yi immediately stopped hiccupping. And the staring just now made Sui Yi endlessly memorable. When she went to take out the trash with Robin, she found the child who bumped into her last time and immediately chased after him. Although Luo Bin didn't know what the situation was, she followed.
The two went to the police station again, only then did they realize that they left He Chufeng at home. The girl insisted on seeing He Chufeng, Luo Bin and Sui Yi were very curious, could she be his illegitimate child?
